Extract

Intravenous thrombolysis in an extended time window has been proposed in anterior circulation stroke based on the presence of a mismatch between the diffusion and perfusion lesions on magnetic resonance imaging (MRI).1 A single report discussed this strategy in patients presenting beyond 4.5 hours with a minor posterior circulation stroke.2 We describe a patient with vertebrobasilar stroke treated 6 hours after symptom onset, using the diffusion-perfusion mismatch paradigm.

Figure.

Magnetic resonance imaging (MRI) was performed at baseline and day 1. A, Axial diffusion MRI at baseline. Arrowhead indicates left lateral mesencephalic and cerebellar lesions. B, Perfusion MRI time-to-peak map at baseline. Arrow indicates cerebellar diffusion-perfusion mismatch. C, Time-of-flight magnetic resonance angiogram at baseline. Arrow indicates left superior cerebellar artery occlusion. D, Axial diffusion MRI on day 1. Arrow indicates mesencephalic diffusion lesion reversal; arrowheads, new cerebellar lesions. E, Perfusion MRI time-to-peak map on day 1. Arrow indicates significant reperfusion. F, Time-of-flight magnetic resonance angiogram on day 1. Arrow indicates recanalization of the proximal left superior cerebellar artery.
